Introduction
Two French agencies have the responsibility
of working out regulation on public
exposure to EMF and enforcing it:
The French agency for Food, Environmental and
Occupational Health Safety (ANSES) assesses
research about the biological effects of nonionizing electromagnetic radiation.
http://www.anses.fr
The National Frequencies Agency (ANFR) checks
that the operators abide by the law before
granting authorization for the installation or
modification of a radio station.

Missions of ANFR
Created in 1997, the Agence nationale
des fréquences (ANFR) is a public agency
in charge of:
Spectrum Planning and International
Negotiations
National Frequency Management
Spectrum Monitoring
On the national territory and overseas
territories.
Missions of ANFR as regards
general public exposure
to electromagnetic fields
To ensure the respect of the limit values of the
electromagnetic field. ANFR agreement is
required before implementation of a new
installation.
To check conformity of the Radio and
Telecommunication Terminal Equipments
(R&TTE) to the European Union regulation
(essential requirements as defined by EU
standards): monitoring of the radio terminal
equipment market.
To keep up to date the measurement protocol
(order) which is used to carry out field
measurements in order to check the compliance
with the general public exposure limits.
French laws
as regards limit values
Decree n°2002-775 (3 Mai 2002) : limit
values for radio stations.
Order (8 October 2003) : technical
requirements for terminal equipments (SAR
limits).
Limit values are the same as in the EU Council
Recommendation of 12 July 1999 on the limitation
of exposure of the general public to
electromagnetic fields (0 Hz to 300 GHz)
(1999/519/EC) and based on ICNIRP Guidelines

EMF in situ measurement
Current version : ANFR/DR 15 v2.1, edition 2004 [1]
Main goal of the new version : to take into account
NF EN 50492 standard
Other important goals:
• Additional quality requirement (a maximum fixed
uncertainty shall not be exceeded)
• Measurement process simplification
• Increased number of accredited laboratories (ISO/CEI
17025)

CASE A
RMS measurement over 6
minutes
Spatial average on 3 points (6
points are possible to reach a
lower uncertainty)
Optional measurements are
possible for different services
(At least : FM, TV, GSM, DECT,
UMTS, WIFI, WIMAX)
Optional measurements

An important criteria for this type of equipment is the

CASE B
Three steps for the testing :
1. Wide band measurement (if case A is not
performed)
2. a) Measurement by services
b) For each services the field levels of
the significant emissions with a spectrum
analyzer.
3. Extrapolation data processing for cellular
networks
Extrapolation for outdoor cellular
networks (GSM AND UMTS)
•
Below 6 V/m [1] :
Statistical safety factors are used [2]
•
above 6 V/m : the extrapolation is used to
check the conformity.
True factor is considered according to a
database (CI and LAC) for cell parameters
which exceeds 98% of the statistic.
 trace mobile is required
[1] the conformity is reached but a case B can be asked.
[2] The statistic includes at least 98 % of the cases.
Cartoradio (http://www.cartoradio.fr)
Database of the results per
location.
All transmitters with EIRP above 5
W are located on the map (except
defense, civil aviation and police for
security reasons).
Access to every file of result :
 Description of the environment
 Detailed results per frequency
 Histogram per service
Update of cartoradio is planned (end of 2011) with a new
ergonomy similar to “geoportail”(www.geoportail.fr) and to take
into account the new protocol
UMTS decoder
Calibration is impossible to perform :
Method is established according to an
agreement between the stakeholders
(ISO/CEI 17025 standard requirement).
Measured value must be within ± 2 dB
relative to reference emissions obtained
with two different UMTS signal generators.
Comop workgroup
COMOP chaired by François Brottes (member
of parliament) studies the feasibility of a
reduction of the public exposure to EMF
through modeling and experimentation in
different towns. COMOP is also in charge to
experiment in these towns new procedures of
consultation and local information.
Inventory for 6 areas in different French towns
has been presented to the general public
(Exposition and QOS simulation and
measurement) :
Paris XIV, Courbevoie, Grenoble, Thiers, Grand
Champ and Kruth.
